Annular BOP

In some coiled tubing applications it may be necessary to
seal on various diameters of the BHA. The annular design will seal on an open
hole up to 5.50” diameter.

The
hydraulic operating piston of the annular BOP is designed to efficiently
actuate the piston, thereby closing the packer and minimizing the effect that
well pressure has on the pack-off. The normal 1,500 psi hydraulic pressure is
the maximum required for BOP operation over the full 10,000 psi working
pressure range.
